Google has now integrated its Flight Search product into general search results:

Here’s what Google had to say about making Flight Search a better and more integrated product:

Starting today, we’ll begin showing flight information right in your Google search results on certain flight related searches. For example, if you search for [flights from San Francisco to Las Vegas] you’ll see a table that shows available flights, including duration and prices. You can adjust dates on the page, or click any flight to further research and book your trip.

Over the next couple days, you’ll start to see the flight results appear for searches whose origins and destinations are currently supported by our Flight Search feature. In the short term, those results are limited to domestic US flights. The flight schedule feature will continue to provide information about nonstop routes around the world and across 11 languages.

I find this extremely useful, since a search for “san francisco to lax flight” used to bring up a lot of ads and landing pages from other ticket purchasing sites. Unfortunately, as of right now you can only find flights within the U.S., but this will be expanded globally as the product grows.
